Twalffulwn it 'nt/,ty concern.' 4nBeit-lmcwvn that I, OscAn WooDWAnn, acitizen-Ot the U 'ted States, and a resident of tlieborough of ltanhatian, city of New York,

rOrk, have invented certain new and useful Impr'oycm'ents in,Type-Viriting Machines, of y which .the tollowing is a specication.`

l vThis invention relates to tabulating mech- ;o anisrns -of writingmachines and more particularly to `that class Oftabulating mechanisms'inwhid-h a series of denomination keys 4,are employed, each of said keyscontrolling a denomination stop, said denomination stop riagejbeingautomatical y released vby -said ley and-.permitted to run freely underthe. tension of the usual carriage spring until ar- ,rested by saidprojected stop at a point Where 2Q thewrtin of a number having thedenomination of tlie operated key may bebegun.-

s jf lhe main object of my invention is to pro- I i' vide'anovelconstruction of the carriage releasing mechanism in .connection with atabz 5 ulat'or of the class described.

j the accompan 'ng drawings, Figure 1 lis a vlan view` luso much of. atype-writmac e asis necessary to a correct understandng of my invention,some of the ii partslbeingbrpken away and other parts bemg shown in'scction Fig. 2 is a side e1evation of the machine, s 'ome arts beingshown ,insecton-andother parts fing omitted and -brkelihityr p -35 Inthe drawings, theframe of the machine 't-,comprises a base 1,-coinerpplsts` 2 ggd a top.; cruin at 5 in 4plate 3. Ke levers 4are vthe rearyof t e base, each ofsaid lileyf-levers lbeing provided with a restoringspringt and being connected jby a link 7..W1th a type'bar rollers',`18"ai`1dl14, which run upon parallel" guider-aile and 1G. A carriagerack 17 is .o/ ,secured to curved supporting arms. 18 pivoted at 19 atthe rear of the carriage V12, and

qs'aid carriage rack normally meshes with a feed .pinion 20, whichlatter is operatively in the county of New York and State of New ybeingprojected by its ke f andthe paper car'- "at its ends in a verticallyarranged frame or "bracket 43, said bracket being-clamped to connectedto an escapement wheel 21lcontrolled by a feed dg 22 and a holding dog23, both of said dogsbein'g carried upon theupper end of .a dog rocker24 pivoted at 25 to a fixed part of the machine. The dog rocker hassecured to it forwardly extending arms. 2connected by hooked-members27with a. 6o universal bar 28 which extends from side to K side of themachine beneath the series of key levers; but only one .arm 26 'and onehooked member 27 appear in the drawings.. l.Vl/'hen the key levers areactuated to cause the ltype oars to print, the universalbar 28 throughthe connections described vibrates the4 dog .rocker 24, causing theescapement members or dogs 22 yand 23`t co-operate inv a known mannerwith the escapement wheel 21 to per- 7o mit the platen carriageto bedrawn leftward a letter space distance under the inuence of a springdrum 29 with 'which said carriage is connected by a strap or band 30which en'- gages a hook lsecured to the carriage. The 7S structure thusfar described isessentially the samees that of the Well known No. 6Rem-y in ton typewriter and it is therefore not consi cred' necessary todescribe the parts in greater detail. i

One or more column stops 32 are dis Osed along a column-stoprack-bar 33which' ex-j -tends parallel'with the platen 11 and is suite. A ablysecured upon the ends of arms 34; ,rojecting rearwardly from a'bar 35,the latter $5 having downwardly extending ears 36 whichy i are suitablysecured to the axlesl'of the rear rollers 14 of thel platen carriage.- I)zenomina vtvoustops 37v are arranged at letterY space intervals apartandsufiicently'in' the rear of 9 `"the column-stop rack-bar '33 tonormally clear the column stops 32,'said' denomination stops 37' beingformed at'the upper ends -of vertically disposed levers 38fgpivoted on affulcrum rod 39 and connected at their lower ends withhorizontallydisposed push rods- 40, the latter extending .-.iorw'ardlybeneathv the base 1 and carrying at their'ffro'nt-ends keys 42. Theulcrum .rod 39de supported the base of the machine by -set screws 44'(one only of the latter being shown) and be connected near its upper endby a screw 45 with a U-shaped supporting membelffi, `xo5 which member isin turn supported,attire xo ing mechanism as thus far described isgenerally similar to the well-known Gerin tabulator, and for thepurposes of my invention it is not deemed necessary to here describe theparts in greater detaill Above the fulcrum rod 39 the supporting frameor bracket 43 is formed with a forwardly and upwardly prf'g'ectingportieri 5l which is provided with vertical kerfs or slots 52. Eachslot'52 receives a bell crank lever 2o 53 fulcrumed on a fulcrum rod 54which exl tends from side to side of the part 51,. The number of bellcrank levers 53 corresponds to the number of denomination stops, whichnumber is ten in the particular tabulator illustrated herein; but thenumber of denomination stops Aemployed is immaterial. The upwardlyextending arm of each of the ten bell cranksj53 is formed with a slot55. l Engaging-said slot is a'pin 56 secured to 3o and extendinglaterally from a short ear 57 integral with the associate denominationstop lever The forwardly extending and horizontally .disposed arms ofthe bell-V l crank levers 53 are off-set laterally as ap- 3 5 pears inFig. l,- ive of said bell crank arms or half the entirenumber being bentor offset to the left of the escapement Wheel 21 and the remaining halfbeing bent to the right of said wheel. The forward end of 4o eachlhorizontally disposed bell crank arm is bifurcated as indicated at 58,the bifurcated portion engaging with a pin 59 projecting laterally fromthe rear end of a littinfr lever 60. There are ten of these liftingllevers, lone for each bell crank, and they are divided into two groups,one group comprising five of the levers being arranged at the left ofthe escapernent whee 2l and` its bearing andthe other ve levers beingarranged at the right 5o thereof. Beginning at thc rear end the leversof each group irst 'bend laterally outward, these lateral bends 60 beingsucceeded by portions 60b extending straight toward the front of themachine, the portions 60b being followed in turn by portions 60 whichbend inwardl toward the center of the machine. The orw'ard end of eachlever 6() is formed with a horizontally arranged lip or lifting shoe 6,1which normally stands be- 6o neath and out of contact with the carriagerack 17.v `As appears in Fig. l, the two groups lof lifting shoes 61 arearranged so that the 'members composing each group are closetogetheL-gthe innermost-member of 65 each group beingbut a shortdistance from the feed pinion 20. Bearingiy brackets 62 and 63 aresimilarly secured by headed screws 64 to the top plate ot the machine,each bearing bracket being slotl ted or kerl'ed to receive the portionoi a ill the lifting 7o levers 6l) save thexinnermost lever ofa eachgroup. .The levers 60 move jeely in their slots in the bearing bracketsari d are pivoted on short fulcrum rods 65. T hl e inner endof eachiulcrum rod 65 is prol 'ided with a 7 5 fixed collar 66 abutting the inner lifting lever'60 of the group, said inn r lever being arrangedbetween the collar li and the .end of the bearing bracket. The? outerend of each'rod 65 is threaded to rec eive a iiut 67 8o which assists inretaining the n :id in place.

When it is desired to operatir the tsfbulat ing mechanism the properden" n'inati l nkey 42 is pushedin, thereby, actua ting tl' ciate lever38, the lever arm of said lc ver be.- 85 ing swung rearwardly about theuli ruin 39 and the upper arm of said lever bein swung forwardly aboutsaid fulcrum; the 1 `sociate denomination stop 37 being thereb movedforward to 'operative position.. i, As 1he upper 9o arm of the lever 38moves forward ij'actuates the associate bell crank lever 53 tlfuough thepin and Vslot connection 55-56, swinging the orizontally disposed armothe 'bell crank lever downwardly about the ful'crllm 54, said 95horizontally dis osed arm in tur ,'n acting on' the associate liftinglever 60 tos'ringt-he re'ar arm of said lever downward aloout'th f11l`,crum 65and the forward arm .lofrsaidlever upward aboutsaid fulcrum.4Ijs the `foi-wand 1o arm of thelifting lever is swung upward the lip orshoe'61 at its end contacts with' thev carriage rack 17 and swings [thelatter upward about the pivots 19.unt `il said rack .dle-

"engages from the pinion 20. i .As soon as the xo' rack is se arated.from the pinion, the caff-- riage 12, ed' or released 'from theescapement devices, is drawn leftward across the' top plateby the springdrum 29, thisrffee movement of the carriago continuing until n thecolumn stop 32 coacts the projected' denomination stop 37. The ke '42-isthereupon released an the paltsof' e'tsbulaltin mechanism actuated bsaid'key'am rest ore to non'nal position by t esp 49,'-while the rack 17is caused to re-en gage with the pinion by the usual racksprin'gmotshowii). .TheA desired characters may then 'lie 'printed in aknown manner and theigeafter fthe tabu sting mechanism may be again4operated the 12 mannerdescribedto release or free tlle car 'riage fromits esca ment devices and said carriage to A drawn freely lo until thenext colline- 1 stop coacts with projected denomination sto ""ifka Itwill be observerlthat by myl constnrction I provid aseries ofdenominationjkeys, each of said eys beingadaptedto oprata'anassociatedenomination sto nember? and also to operate an associate eviceforreleasx3 'ing the carriage v0i the machine from the es.- capernentdevices; that each of said rele'as ing -devices. ,is separate from allthe other releasing devices and is operated by the de- I'iomination keywith which it is associatedindependently. of all the other releasingrdevices.

v `While I have 'shown my invention as cnibodied the tabulatingmechanism comr'monly known as the Gorm tabulator and as applied to theNo. 6 Remington typevmiting machinej-it is to be understood that said invention may be adapted to other styles of tabulating mechanisms andwriting machines, andthat'various changes in-the construction and in thearrangement of the parts may -effected' without departing from thefspi'rit oft'he invention.
